Abstract

Three-component displacement time histories on the surface of near-field fault are obtained from analytical calculation of seismic moment release rate function and energy center source model. Analytical strong motion are compared with the strong motion records in meizoseismal area, the results indicated that, during Ludian Ms6.5 earthquake rupture process, NW-SE fault is the main seismogenic fault even if conjugated NE-SW direction fault also play the role in. This proposed method of using seismic moment release rate functions and strong motion records to determine comprehensively the dominant seismic fault direction, also can be used for other seismic event.
